UI 3.0 and Old UI
Besides the look, the main difference between UI 3.0 and the Old UI is that UI 3.0 uses a new PDF Viewer and Annotation module, which is much more stable compared to the one in the Old UI.
By default, Real PDF Suite switches to use the new UI 3.0. However, if you prefer to using the old style UI, you can always switch it back to the Old UI.
Click the button or menu item “Setting” and then you can do your selection in the UI Settings window.
Note: we highly recommend you use the default UI 3.0 because we may get rid of the old UI in the future.
Besides PDF, Real PDF Suite can also open many other formats. It works well as a e-book reader and a image viewer.
The formats are: PS (.epfs, .epfi and .ps), Tiff (.tif and .tiff), CHM, DjVu (.djv and .djvu), Images (.bmp, .dib, .icb, .ico, .jpe, .jpeg, .jpg, .jpg2, .mng, .png, .pbm, .pcx, .pgm, .ppm, .rgb, .tga, .tpic, .vda, .vst, .xbm, .xcf, .xpm .gif, .webp and etc.), DVI, XPS (including .oxps), ODT, Fiction Book (.fb2), Comic Book (.cb7, .cbt, .cbr and .cbz), Plucker, EPub (.epub), Fax (.g3 and .fax), Mobipocket (.mobi), Okular, Prc, Wwf
